How to write machines

Maths fun was had by all

Last weekend I was in Gothenburg at the incredibly inspiring Free Society conference FSCONS. Of course I was talking about mathematics, specifically how to get people learning it through fun, rather than “because it is useful”. My talk was called “Street Maths” (click for slides).

In discussions with many including Smári McCarthy and Marcin Jacubowski the idea developed further and one result is this (highly opinionated😉 manifesto for literacy.

In 1964 Paulo Freire was arrested and exiled from Brazil for teaching peasants to read. Both sides recognised the power of literacy, as a threat to oppression and a path towards a better life for individuals.

Today in the developed world we take it as an essential. Those who cannot read are not merely marginalised but kept out of society. Yet new skills are becoming necessary. Our formal interactions are now almost more likely to be through a computer than a pen. This change is sweeping through so fast that it can be hard to keep up. We have all joked that the kids teach the adults how to use the latest device.

Lets give the education system its due. The schools curriculum in the UK recognises that for Information and Computer technology (ICT):

Think about these for a second as we consider the skill of literacy. It has two parts. Reading is of course important, but teaching people to read only allows one way communication. We also teach to write. We are taught to use written content, but also to create it. Think about this as you again read the list above. It only talks about learning to “use” ICT.

We need the skills to write and create as well as simply use. Firstly, for some a bright idea will result in a new use for computers. Just as for some the ability to write leads to a published book. For others some simple creations will help their lives or those close by them, just as some write diaries. Finally there are many who do not write much at all. Yet learning to write writing still helps us develop our reading. The same is true for technology, but it is even more essential. Reading is a fixed skill. A language develops too slowly for reading skills to need much change. This is not the case with computers. The skills to use a particular piece of software can change with a single upgrade, even when we are not forced to change to a more advanced competitor. The usage skills therefore can easily go out of date. The more fundamental skills teach not just the skills to create but the ability to learn; to adapt to rapid changes.

So what skills are needed to create technology? Programming is obviously first. There is, however, a lot more to technology than computers. There are a vast number of ways that gadgets can be used, and will be used. Should we leave people waiting for someone else to make something close enough to what they need? What about adding the basic skills to make things?

Unlike literacy and use of computers these are not new skills. They are in fact ancient. Not a very long time ago if you wanted something you either had to make it yourself, or go to someone who could make it for you. Then we had the industrial revolution. The economy of scale. We came to rely on factories. This now goes so deep we hardly think of making something ourselves. For truly mass items like a hammer or a car, we are probably right. What about a more specialised device though, like say a tractor? Or a 3d printing machine? Here plans are freely available that require some skill, but not expertise, to build. Including money for building time the product can be made for a fraction of the cost (in many cases 1/10 or less). Even better, with such open design comes a powerful new option. Take the generic solution and adapt it to your own situation. With time the design improves as individuals using it make refinements and add options. To do this takes a certain mindset and some basic skills. A literacy of making.

The natural response to this is that, on top of the skills, tools are required and those tools are themselves prohibitively expensive. Though this is true right now, it is changing. Movements such as FabLabs and Hacker spaces have the tools and make them available for free, or at a small cost. Even better, the machines can be part of the change. One of the machines above is a 3d printer, this is not just cheap to produce, it is capable of making itself. The development of other machines has begun, with the ambitious goal of creating a RepLab a multipurpose factory that can create itself at a cost of less than $10000. Even commercially the machines only cost about $100000. Things are changing. Fast. The question is can we get the people in place with the creativity and skills to take full advantage of them?

I agree that more creativity needs to go into using ICT for teaching. Part of the problem is that policymakers (mostly humanities graduates) don’t really know what ICT is, and think it just means MS Office. How depressing being taught how to use Word at school! I don’t believe they have even appreciated the skills which are important for ICT.

I think its a little unfair (but not completely😉 ) to blame the humanities. There are technical issues, but more broadly no one knows where these things are going. The argument is that it is better to equip people for change than to try to find some stable state.
